To all 'whom it may concern:

Be it known that I, -N EWELL VPall/LIX, a citt zenof the United States, residing at Avenue, in the county of Franklin "and State ot' Ohio, haveinvented certain new` and useful Improvements inWindmills, of which the lfollowing is a specification. e

The objects of lniy improvements are to obtain a strong and compact construction of turntable, and its connection with the tower-bed; to provide a incre compact arrangement of plunger-rod inrelatior'i'to the tu'rnftable, and in relation to the connections for controlling the Wheel-Wings -for turning' them in and 'out of the Wind, 'andto render' the operation of the mill more reliable.

Referring to the `accompanying drawings, Figure l represents rny improved Windmill in elevation, a portion only of the tower being shown ,Fig 2, a sectional view on an enlarged scale, showing thespider and sliding sleeve of the Wind-Wheel, andA the v'telescoping connectionof the hub thereof with thetubular bearing-arm` of the turn-table -for tlie wheel-shaft; Fig.3, a sectional View on an enlarged.' scale,

"showing `the 4vertical tubular spindle of fthe turn-table, its tubular beds, and the relation there'withLof the tubular plrun ger-rod and the connecting-rod-tfo'r cotrollingthe Wheel-Wings; and lFig. 4, the crosslh'ead which serves to conifnect' th plunger-rod with the pitman ofl the Wheel-shaft. i

l The tower consists ofour posts, A, convergf ing? to and inclos'ingf at ltheir upper `"ends, the vertical tubular bed B for the turn-table, and

e to which they are ifirmlybolted, the said bed havingrlug's b formedon eachendffortli'at purpose. 'ilThe vertical spindle part TV 'of -`the turnlthablelis seated within thisbecl, and for `this purpose said bed4 hasaii4 interior` bearing at each'end, Which,'whilelreducii1`g thefricti'n, gives aneftective bearing to thespindle. :The tubular bedhas jrim, 5112, on its iipper`e`nd, andthe tubularspindle has a collar,l lo`1fl,'vvhich,

resting upon the rim b2, supports the turn-table and allows it toturnfreely underuthe laction of thewind upon'fthe Wheel. `Thespindle?bear- "ing part of theturn-table passes" throughthe tubular bed a sufticie'nt distance to receive a screw or stop, t', Fig`."3,lon its lower`end,`to prevent the turn-table from being lifted from its @and the plunger-rod is screwed therein.

tubular bed by the force of the wind.4 AThe turn-table is cast With a horizontal tubular arm, T', which receives and supports the shaft N of the Wind-Wheel,being provided with interior bearings at each end for that purpose. The vertical spindle part T is also tubular, to receive and support the tubular plunger-rod c, and forthis purpose it is providedwith interior bearings at each end, while the tubular plunger-rod receives and supports the rod It, which connects with and by which the Wheel-wingsV AW are controlled, thereby giving a compact and durable construction and arrangement of these parts inwhich one is within and sup ported by the other. The spindle part extends, some distance above its connection with the tower, and it is from this part that the tubularlbearing part T for the wheel-shaft extends so as tosupport the Wind-wheel clear of the tower, and to form a long bearing t'or the proper Working of the plunger-rod. VThe horizontal tubular arm T joins the spindle part T at the side, as shown more clearly in Fig. 3, and is braced at the junction, as shown in Fig. l.

The tubular plungerrod 4e extends through the spindle part, and is provided on its upper end with -a cross head, d, shown in detail in Fig. 4, the arm ot' which is connected, through the rod b, with the crank a on the Wheel-shaft, to give the reciprocating motion to ,the plunger-rod. The cross-head has an interior screw The rodR passes through the plunger-rod, and has al return, r," or arched upperfend, or equivalent ,connection above said' plunger-rod, Which extendswdovvn, and is connected, by a loose joint,

to an angular lever, L. which being pivoted to a`Rfulcrum'Jarrn,.F,pcast upon the tubular arm, has its forked end turned down and connected,

b'y loose joints,`to the strap dof the sleeve D, on which the oscillatnghubH is arranged,

'and which connectswvvith the wheel-Wings W by the extension-rods E, so7 that` the Wings, beingiloosely hung tothe spider-spokes S', they "are,by"the connections des,cr,ibed,.tnrned in and out ofthe wind s required .forstoppin g I a`nd` `starting the mill.

The spider'S is formed with a tubular hubextension, S2, which telescopes with and revolves over "the outer end` of the' tubular arm T` by its tixed connection with the outer'end of the IOC wheel-shaft, thereby inclosin g the outer end of the shaft and its supporting turn-table arm. This tubular hub-extension S2 carries the sliding sleeve D, which in turn carries the oscillating hub H, the inward sliding movement of said sleeve being limited by the stop h on said hub-extension, and the sliding sleeve being connected to the hand-operating connectingrod R by-the lever L, for controlling the windwheel wings. The hub-extension S2 has no interior bearing upon the turn-table arm T', but the wheel-shaft has an interior bearing at the outer end of said arm, which gives a very regular and easy action to the wheel. The tubular hub-extensionS2 does not touch the horizontal tubular arm of the turn-table, but is large enough to leave a space of about three-eighths of an inch between its inside and the outside ot' said arm. The spider S, of which the hub extension S2 is a part, is keyed to the shaft N, and the latter has its bearing in the outerend of the tubular arm, whereby the tubular hubextension revolves over and free ot' said arm, and thereby relieves all friction between these parts.

The plunger-rod e is connected to the rod g by a swivehj', so as to turn with the turn-table without turning said rod g, while the rod It has a swivel-connection, 7c, with the rod It', which is jointed to one end of a horizontal lever, L', pivoted to thetower, and jointed at its other end to the hand-operating rod It, which leads to the ground, whereby the rod B may turn with the turn-table without affecting its hand-lever connections. The arms of the spider to which the spokes are attached are slightly inclined inward to bring the weight ot the wheel-wings W in position where the outer shaft-bearin g can best support them. The Weight of the rod R about balances the combined weight of the rods R' R2 and lever L, as they are supported by the lever L', which obviates the necessity of fastening the rod R2 to either keep the wheel-wings in or out of the wind. y y

As a means of balancing the millon its tubular bed, I provide a counterbalance-arm, C, secured to and projecting from the spindle T, opposite to its shaft-bearing arm T', and having a weight, C at its outer end. A truss-brace, O2, connects with a lug on. the turn-table arm T', and passing over a projection, Z, at the top of the spindle T, is secured to the lever O at or near its weighted end, to aiord the proper support to the counter-balance.

To stop the motion of the wheel the rod R2 is pulleddown,whioh,throughtheleverL',pushes up the rods R' and R, and the long end of the lever L,which, by its forked connection with the sleeve D, draws it, with the oscillating hub H,

spirally toward the tower and against the stop h, which pushes out the extension-rods E and causes the wings to turn their inner ends from the center, so that the slats of the wings are Aparallel with the wheel-shaft. Reversing the movement of the rod R2 reverses the movement make the rod R in one piece, and the fulcrum F, instead of being cast integral with the tubular arm T', may be bolted thereto.

By passing the tubular plun ger-rod through the tubular spindle of the turn-table, a supporting bearing at each end thereof is obtained for said plunger-rod, and the latter thus supported serves to support the hand shifting-rod and to render the working of these parts more satisfactory.

The tubular bed B is firmly secured to the tower by the lugs b', which project radially from the upper and lower ends of said bed and fit between the posts A, and are bolted thereto by the bolts b3, as shown in Fig. l, so that the bed cannot be turned under the action of the turn-table, and the top of the tower-posts are thereby firmly secured together.

I claiml. In combination, the vertical tubular spindle T of the wind-wheel turn-table, its tubular bed B, the tubular plunger-rod e passing through and supported by abearin g at each end of said spindle, the hand shifting-rod R, passing through said supported plunger-rod and supported by it, and the tubular shaft-bearing arm T' projecting from said spindle, substantially as described, for the purpose specified.
